SMIQDigital Standard 3GPP W-CDMA (FDD)2.14.2.6 WCDMA/3GPP Menu - MS Configuration SubmenuThe channels for each mobile station are configured in this window. The operation in the uplink waschanged due to the extension to 3GPP version 3.1.1. In contrast to the 3GPP versions 2.0.0 and 2.1.0,there is no longer a large channel table with 128 DPDCHs. A mobile station has now 6 DPDCHs atmaximum, the parameters of which are prescribed to a large extent by the standard. In order to obtainclear and simple operation, distinction is now made between 3 modes in the uplink (PRACH only,PCPCH only and DPCCH + DPDCH). In each mode, only the relevant parameters are displayed.Fig. 2-119 DIGITAL STD – WCDMA/3GPP – MS CONFIGURATION menuParameters that are globally valid for current mobile station:MS 1(2,3,4) STATE ON The MS is active. All other parameters are active.IEC/IEEE-bus command :SOUR:W3GP:MST1:STAT ONOFF The MS is not active. The other parameters are ignored.IEC/IEEE-bus command :SOUR:W3GP:MST2:STAT OFFMS MODEMode in which the mobile station is to operate. Depending on the mode, thelower part of the panel changes. Only the parameters relevant to the currentmode are displayed. The following modes can be selected:PRACH only In this mode, the MS generates a single Physical RandomAccess Channel (PRACH). This channel is required when acall is set up from the mobile to the base station. The specificparameters of the PRACH can be set according to the sectionPRACH Settings (see further down in this section).IEC/IEEE-bus command:PCPCH only:SOUR:W3GP:MST2:MODE PRACHIn this mode, the MS generates a single Physical CommonPacket Channel (PCPCH). This channel is used for thetransmission of packet-oriented services (e.g. SMS). Thespecific parameters of the PCPCH can then be setaccording to the section PCPCH Settings (see furtherdown in this chapter).IEC/IEEE-bus command::SOUR:W3GP:MST2:MODE PCPCHDPCCH + DPDCH This is the standard mode of the mobile for speech anddata transmission. The MS generates a control channel(DPCCH) and up to 6 data channels (DPDCH). Thechannel-specific parameters can then be set in thesections DPCCH Settings and DPDCH Settings (seefurther down in this section).IEC/IEEE-bus command::SOUR:W3GP:MST2:MODE DPCDCH1125.5555.03 2.199E-9
